Answer:
220
Step-by-step explanation:
Now, I'm not sure if 220 is correct, but I'll explain my reasoning.
We know three angles of a triangle add up to 180 degrees.
So, the smaller triangle has 70 degrees and <em>a</em><em> </em>and <em>b</em><em> </em>variables. By virtue, <em>a</em><em> </em>+ <em>b</em><em> </em>+ 70 = 180.
So, <em>a</em><em> </em><em>+</em> <em>b</em><em> </em>= 110.
Likewise, when you look at the whole triangle, 70 degrees is also one of the angles while <em>c</em><em> </em>and <em>d</em><em> </em>are unknown.
So, <em>c</em><em> </em>+ <em>d</em> + 70 = 180.
This means <em>c</em><em> </em>+ <em>d</em><em> </em>= 110.
So, <em>(</em><em>a</em><em> </em>+<em> </em><em>b</em><em> </em>) +<em> </em><em>(</em><em>c</em><em> </em>+<em> </em><em>d</em><em> </em><em>)</em><em> </em><em>=</em><em> </em>
110 + 110 =
220 degrees.
I hope this helps!

Answer:
The mistake is evidently in the addition of the first 5 bowling scores
Step-by-step explanation:
Brenda had bowling scores 92, 110, 85, 78, and 96.
She needs one more bowl to get an average of 96.
Let the last bowl score = x
(92 + 110 + 85 + 78 + 96 + x)/6 = 96
(92 + 110 + 85 + 78 + 96 + x) = 96×6 = 576
461 + x = 576
x = 576 - 461 = 115
The mistake is evidently in the addition of the first 5 bowling scores, the score for the 5th bowl was excluded, maybe because it was coincidentally 96 too.
She added (92 + 110 + 85 + 78) instead of (92 + 110 + 85 + 78 + 96), so, the score needed for the last bowl to get an average of 96 is actually 115, not 211.
Hope this Helps!!!
